LG CE-20J3GGX sasiu MC099a probleme

Recommended Posts

Buna ziua!Am acest tv la care se apronde ledul rosu ,dau sa porneasca ,apare sonor pentru o secunda apoi  pica inapoi in st-by.

Dupa niste masuratori,sursa pare a fi ok dar nu apar impulsuri pentru tensiunea inalta.

Dupa un timp cateodata porneste ,si merge toata ziua.Dupa ce se raceste nu mai da sa porneaca inalta tensiune.

Stie cineva acest defect,s-ar putea sa fie tipic acestui sasiu.

Va multumesc.

Am incalzit Tda8842 si apoi l-am racit.Tv porneste instant.Apoi iar l-am incalzit si asa nu mai porneste.Am dat cu spray de racire iarasi si porneste.

Sa fie defect TDA?

 

 

p.s. se pare ca daca dau pe partea cu piese atunci porneste,ciudat.poate vreun smd sa faca fite.
